US President Donald Trump said Friday that a deal has been reached to reopen the US government and that he would sign a bill to fund the government until Feb. 15.

"We have reached a deal to end the shutdown and reopen the federal government," Trump told an impromptu press conference at the White House, adding that he will sign a bill that will fund the government for three weeks, leaving more time for the debate on a border wall.

He said a "bipartisan conference committee" of lawmakers from the Republican-held Senate and Democrat-controlled House of Representatives would set to work on the issue of border security, with wall financing at the top of their agenda.

Leaders of both Republican and Democratic parties applauded Trump's announcement. Senate Majority Leader Mitch McConnell said he was glad a deal was struck, while Senate Minority Leader Chuck Schumer said there is "good faith" to reach a funding deal for the border wall.

The partial government shutdown has entered its 35th day, breaking the record of the longest government shutdown in US history. Over 800,000 federal workers have been affected by the shutdown, many of whom were furloughed or forced to work without pay.
